NIGP 691: Power Transmission Equipment: Electrical, Mechanical, Air and Hydraulic

NIGP 691 Power Transmission Equipment: Electrical, Mechanical, Air and Hydraulic, Class code, encompasses electrical switchgear installation, motor control center replacement, compressed air system upgrades, and generator/transfer switch equipment at municipal utilities, water treatment facilities, transit authorities, and county buildings, with state and local buyers across California, Florida, Connecticut, New Jersey, Oregon, and Texas issuing bids through mid-2026. Recent state and local activity shows mixed issuing-body participation: transit authorities and county public works departments are active buyers (Collier County for fuel-station electrical expansion and transfer-switch upgrades, Orange County for water reclamation facility electrical and mechanical upgrades), city utilities departments procure compressed air and blower system improvements (Orlando Water Conserv II WRF blower improvements valued at approximately $4.96 million, City of Orlando water reclamation facility electrical and mechanical upgrades), and county airport authorities source equipment for facility upgrades (Orange County and Ocean County airport projects). Work under this code splits between turnkey equipment installation with engineering design services and repair-and-replacement projects within operating facilities, often requiring 24/7 operational continuity and coordination with utility providers or facility operators.

Representative recent opportunities include the City of Meriden, Connecticut issuing IFB B027-05 for furnish-and-install of a new 800-amp automatic transfer switch at the Police Department with bids due July 30, 2026, and the City of Orlando issuing IFB26-0370 for Water Conserv II WRF BNR System Blower Improvements—a $4.96 million project encompassing demolition of five existing turbo compressors, installation of five new units, roofing replacement, and electrical/controls upgrades with bids due May 20, 2026. Orange County, Florida issued Y26-604 for Eastern Water Reclamation Facility electrical and mechanical upgrades including neutral grounding resistor replacement, 15KV switchgear modifications, and three new EPA/RICE NESHAP-compliant diesel generators with bids due April 30, 2026. Most recent activity clusters in Florida (Orange County, Collier County, Palm Beach County), California (Sacramento County, City of Palo Alto), Connecticut (City of Meriden), and New Jersey (Ocean County), with prevailing wage, Davis-Bacon, and Buy America requirements common across jurisdictions; federal funding and local utility coordination are standard procurement elements in this code space.
